[Q] USB not working after Froyo

After I installed Froyo on my Captivate, USB is not working. When I connect it to my Win7/64 and Vista/32, I get the "USB device not recognized" on the computers, regardless if I am in USB debugging or not. I reinstalled the Kies s/w in the hopes that the drivers would then recognize the Captivate, but that doesn't work. So obviously USB tethering and Mass Storage are not working. Has anyone else had this problem and how can it be fixed? Thx in advance!

Have you tried mounting the phone in debugging mode? This has always worked for making the drives accessible.

Yep, I stated above that I tried with debugging on and off, and it didn't matter. Usually the phone would mount differently with it on or off, but now it's just not recognized. Very strange...

have you tried using a different usb port? i was having the same problem and got it to work when using a different usb slot

I'm having the same problem. It also often decides not to recognize when I've plugged it in to charge. Used 2 different usb cables, 3 different usb ports on my tower, usb ports on 2 different laptops, and plugged in using the stock usb cable/charger combo. I'd like to flash a new rom, but obviously that's not an option for me right now. It double sucks, cuz I just did a factory reset. I also tried the above suggestions to no avail
EDIT: When I unplug the phone while charging (once I finally get it to recognize that it's hooked up and should be charging), it still shows the battery icon as being charged

same problem. sort of getting mad. i have tried lots of stuff. un install re install drivers a couple times now. both pre select and post select usb modes on the phone well any way lots of stuff. all the usb plugs, tryed putting the plug in the pooter first then the phone on all ports. phone with sim in/out all ports and memory card in/out all ports i reall want to try darky's rom. as sweet as xxxbunker.com is with flash on the phone, i would trade it back for 2.1 so i can use my headphone jack for speaker phone again. please some one help
#edit: my wifes phone still works fine on mounting with the vista pooter. she still has 2.1#

[Q] USB Not Working =[

This has been happening ever since I flashed my phone a second time. First time was from stock to MIUI (USB worked with MIUI), but when I flashed it to I think GB it just stopped working. Whenever I plug it into my computer, all it does is charge my phone... I tried multiple USB ports, none of them work, all of them just charge my phone... Help?
EDIT:
I just restored my phone, I'm on Firmware 2.3.6; Build#: GINGERBREAD.UCKJ4

Try changing cable?

same thing pretty much, but with a stock rom.
about a week ago my phone would not charge from an outlet very well, it was like i didnt even have it plugged in, it's gotten worse since then...
when i was able to get it to charge from a wall outlet it would go into usb mode, and that was if i was lucky.
now it wont even charge from a wall outlet and i have to charge it from my computer.
i would try to update my phone to the new 2.3 version but my computer wont recognize my phone, i keep getting an error message saying "One of the usb devices attached to this computer has malfunctioned, and windows does not recognize it."
i've tried to put it in kies mode and debugging mode and the rest of the modes allowed but still nothing.
i did a factory reset and it still does the same thing(and i lost EVERTHING on my phone but my contacts)
any ideas??

I have the exact same problem. I have tried installing Kiesmini, the samsung usb drivers directly and tried on mac and pc with different cables.
The cables function normally with blackberry's and samsung galaxy ace but the infuse refuses is not recognized by the pc. also the phone does not recognize that it is connected which usually shows a prompt for USB.
Any help will be greatly appreciated.
P.S. I am on 2.2.1 stock Froyo and I am unable to root because of not having connectivity to usb through the computer for Superoneclick to recognize. Also, i tried z4root several times to no avail.

[Q] Cannot get pc to recognize skyrocket

So my girlfriends little brother gave me his skyrocket. He asked me to backup his pics, which I did with no problem. I then did a factory reset. After that, my computer does not recognize the phone! I've tried different cables, different computers. My girlfriend has the exact same phone, connects right away.
I even flashed it with a different rom and put ICS on it. No luck! I then proceeded to take it to a phone repair place, thinking it might be the actual usb port. They said they checked out the port, and it look fine. All solder joints were good, no bent pins.
The weird thing is, is that it connects on an average of 1/20 times! It charges perfectly too. The phone doesn't go in and out of charge mode if i wiggle the cable either. I'm kind of confused! Is there a file on the phone that tells the computer what it is when connected? If so, can I manually replace that file? WHAT DO I DO!

When you goto recovery mode can you goto mounts and say mount usb? and does the pc recognize it then?

Kind of. We had trouble with it when flashing it. I personally didn't flash it. I watched my friend do it

You could try installing the drivers again..

You mean on the computer? I did that. No luck. It does connect more often though WITH the drivers.

I had some problems with USB connectivity too. Using the cable that the Skyrocket came with solved my issues.
Have you tried any combination of restarting and reinstalling the drivers?
Swyped from my Nook Tablet, running CM7.

Yes. I've tried multiple cables including the stock cable. Installing drivers, restarting both devices. I have definitely ruled out the cable, the PC ( PC's actually), and the physical USB port.

I had similar issues, messed with phone for a bit and came up with this
System settings>more>USB utilites
Now I got a screen that says USB mass storage with a button that says Connect storage to PC. Tap Button.
A window will pop up asking to Turn off USB debugging (if on) Tap OK
Connect USB cable to storage (plug USB cord into PC).
You should now be at the USB Mass Storage screen, Tap button at bottom (Turn on USB storage)
I found this to be the way to turn on Mass Storage since I flashed ICS, I believe. Hope this helps you, it took me a little while to figure out.

Of course, that's how it's always been except in a slightly different location on ICS

I've tried that also. Didn't work
Sent from my SAMSUNG-SGH-I727 using XDA

it basically sounds like the USB port on the phone is dead. Warranty that sucker

I took it to a repair shop. They said the port was perfectly fine!

Not to mention that it was working perfectly before I did the factory restore
Sent from my SAMSUNG-SGH-I727 using XDA

how exactly did the repair shop test it?

try plugging it into another usb port on the same computer or try using a different computer. It could be the usb port on the PC itself.

That's the first thing he tried, it's in the OP

yeah i've tried everything! The repair shop determined that the port was good by examining it under a scope and they also said they tried re-flowing the solder joints. They said they wanted to stay away from replacing the usb port because it was very difficult to replace, not to mention they didn't warranty the job!

Someone has to know the answer to this!
Sent from my SAMSUNG-SGH-I727 using XDA

if its still under warranty replace it, thats all u can do. No one else in this forum besides u can physically touch the phone, so if you've tried all suggestions thats all thats left

i have the same problem but mine is little different, when i power off the phone it keeps on going to download mode, i keep on restarting it and it goes back to download mode, i flash stock rom and it does the same, i flash ics rom and it keeps on doing the same can anyone help?

Phone not being seen by any PC

So this issue started a few days ago. Any time I plugged my phone in it would constantly connect and disconnect from the pc. I've tried multiple usb cables, ports, and the 3 PCs I have with the same result on each. Now when I plug it in, it is no longer being recognized by the PC, Odin, ADB, etc... It will charge but that is it.
I have a warranty replacement coming to me however I need to be able to get this one back to stock... Any suggestions?
Before anyone asks, NO it has never been wet, dropped, damaged in any way, set on fire, caught in a land slide, earthquake, what have you.. The phone itself functions perfectly fine. All drivers are up to date, none of my PCs configurations have changed. I have one I use specifically for app development and not even that one will see the phone.

I had the same problem. I used a different cable and it all worked better....now with that said it happened again so I flashed my phone back to stock and all was well.
Then went to flashing ROMS.

Really check out the micro usb cable. A bad cable will just about always allow a device to charge, but data transfer is another story. If you really have tried a few micro USB cables, then it the problem relies elsewhere. Try restarting both phone and PC, and if neither works, sounds like you have a busted port on the Skyrocket.

Thank you both for your responses. I am a PC technician so I followed my usual troubleshooting steps to figure this out. I narrowed it down to either all of my cables are bad (not a chance) or the phone is just f**ked (likely). Ah well ill have to try to use another way to force the stock firmware and recovery on here. Lol
HTC = Hate The Consumer

I use my old Nokia OEM USB cable. Connects with the right number of pins on the USB connection end. I'd check your USB cables for # of pins . Skyrocket uses 5 I believe. Also that there is sufficient power to your USB ports. Aka avoid front USB ports which could only be 4 pin....
Sent from my I727 rocket on Marz! @[email protected]

When you plug the usb cable in, do you see the usb icon at the top left of your screen? I have to pull that window down to tell it to connect to pc, then confirm it again before mine connects. Mine doesn't auto connect on its own.
I see you've been a member for a few years so if its not connecting, that really sucks man. Hope you get it figured out.

Not running the AOKP ROM are you? The R3 build had an issue with this, and all AOKP will disable USB to PC if you enable 'fast charge' under ROM Control...
Good luck :S

According to what I've been reading you can try using the *#7284# code and setting the USB portion from PDA to MODEM and then back to PDA and it would kickstart the connection. No dice for me though. Ive been through 7 different USB cables already.. I am not about to go and buy one just to keep playing with it my other phones connect just fine using the same cables. No, I am running the latest Sky ICS

Infuse 4g USB problem

When I plug my USB cable into my computer and then into my phone the phone does not recognize the computer and vice versa. It will charge, but that is it. A few weeks ago I tried an AOKP rom which has "fast charge" I set this setting to be on to test it out and then turned it off. Ever since then I have not been able to transfer files with the cable plugged in, so I used AirDroid to wirelessly do it. I remember something in the warning about it, but I thought when you format/wipe and flash a new rom it corrects the issue. I have flashed a completely new rom since then and still nothing. Any help would be nice, thanks.

Try going back to stock through Odin or heimdal

How are you supposed to Odin/heimdall, if it doesn't connect even during download mode?
Sent from my SAMSUNG-SGH-I997 using xda premium

Lol didn't think of that...when I had my infuse I had the same problem with the stock USB cable...after a while data transfer stopped and it became a charge only cable...I would use my dads cable that worked perfect for data transfer...
So try a different USB cord or try a different USB port...

You can try this too
Hi, I faced this issue few times and tried several options like change cable/port/computer and worked.
One thing Recently i noticed when all of the above failed in my case is :- 1 Development->Uncheck the USB debug mode, 2. Check Mass Storage in USB connection setting. ( you need to unplug usb cable while doing it)
Now try connecting and give few minutes. If you can see the USB mass storage notification you are good to go. Go back and change the Debug mode as Checked.
It worked for me couple of times hope it may work for you too.

Sounds like the dreaded USB port failure. Many Infuse users have gone through this as its a known issue. I returned mine and got a replacement via warranty.

Hey There,
We had the same issue with many units and solved all by doing the following:
-Flashing the unit back to stock
-Performing a factory data reset after flashing(This is a must)
Note: Even though your device will not connect to the computer in PDA mode you should still be able to connect in download mode so it can be flashed with ODIN.(Unless if it's hardware related)
